In the NPI registry since
2007

Licensed in Washington since 2012, according to the Washington State Department of Health. We show license dates only for the states that publish them in bulk; see which states do. For other states, check the state medical board.

The NPI date is when this clinician registered for a National Provider Identifier, the billing number used on health claims. It is not a license, graduation or board-certification date. NPIs were first issued in May 2005 and became required on claims in 2007–2008, so an early date usually means the clinician was already in practice before then. What an NPI is

Education and training

  • 2007Medical school: University of Southern California Keck School of Medicine
